The Star Trek franchise reflects, conveys, and comments upon the key philosophical tensions of the modern era: pragmatism vs. justice; universalism vs. traditionalism; empire vs. consensual polity; environmentalism vs. modernity. George A. Gonzalez details the manner in which these tensions and controversies are manifested in Star Trek across its iterations, and in so doing argues that Star Trek offers an indispensable intellectual and analytical contribution to our understanding of the politics of the modern era.
